Peterson was running straight-ahead sprints of 40- and 80-yard distances just four months after reconstructive knee surgery. That doesn't mean he's a lock to start Week 1, coach Leslie Frazier said, but there's no good reason to bet against Peterson being ready. He's driven like few others and guaranteed he'd play Week 1. It might not be feasible for Peterson to be the same player fans are accustomed to, at least early in the 2012 season, considering the offensive line changes and serious leg injury. If Peterson is on the field, he'll get plenty of work. His vicious running style and the absence of a legitimate No. 1 receiver are worrisome but not enough to pass on a player routinely drafted with a top-3 pick in Fantasy leagues just a few years ago.
